Not to be sad on main but…
consider this: Heaven is not happy about the whole Angel And A Demon deal, so they pull some “A Thousand Words” shit where if Aziraphale sees or tries to communicate in any way with Crowley he loses one of his feathers until he Falls, hoping that’ll keep them apart.

I know what you are, David almost said, that day when Frank had him zip-tied to a chair.

I know what you are ... but he didn't say it, though he teetered on the edge of it more than once. He didn't, because he wanted Frank on his side, damn it, and most of all he didn't want to give Frank any more reasons to kill him than Frank already thought he had.

To be born without a Quirk is unfortunate. To be born without wings is pitiful. Without both? Most don’t consider living such a life to even be possible, the odds so stacks against you that it would be better to simply give up.

They've mistaken Percy for one of their own, another angel chained to the material plane. He can hardly imagine a more ironic misconception. “It’s the hair, isn’t it?” he says, raking it back with a self-conscious hand. Theirs is thin, white, and gently curled, like his. “It didn’t start this way. I’m afraid I'm only human, as disappointing as that is."

Prompt: Sirsparklepants asked for: wingfic, the one without wings loves to preen/cuddle the one with them. ...I don't know how I managed to get angst into that, but I'm already failing at my own damn challenge. (In my defense, it's been an increasingly crappy weekend in between bouts of writing, so clearly more writing is called for.)
Spoilers: Captain America: The First Avenger.
Summary: Bucky says it's a hazard of the job, but those hazards are different when you've got wings.

Several years before Sam was born, a Supreme Court ruling decided that those who carried and visibly expressed a hereditary winged trait could not be mutilated, amputated, or otherwise altered without their consent, nor could they be discriminated against for housing, employment, etc. based on their possession of wings.

The world that Sam grows up in is one that remembers when it had been different. [Wing!fic AU.]

Sam went from working at the VA to teaming up with Captain America to assisting on a crew of superheroes. Magic shouldn't be a big step from that, but defending Central Park earns him an unexpected favor, and Sam isn't sure he wants to accept.

Anything that’s not human is a monster but not every thing that’s a monster is monstrous, so what exactly is a monster? And why must something with wings be a monster when it might just as well be an angel?

Dean spends the month after he kills Lucifer adjusting to this new Second Sight shit. Bobby's is either a great or terrible place for this--there's a lot of psychic residue all over the property, which gives Dean the mother of all headaches at first, but he learns to filter the unimportant stuff out real quick which cuts down on the strain. There are certain things he can't filter out without losing the sense entirely, though. The demonic shadow that clings to Sam has been fading, slower than Dean would like but at least it's going. There's a weird buzz in the air every morning before the sun rises and every evening after it sets, the between-times that Dean's developing a proper wariness of. Castiel has wings all the time, and even folded at rest they're longer than his body is tall, so the ends always vanish through the floor.

Rodney McKay, raised by a pod of telepathic whales. John Sheppard, mage with fae blood. Teyla Emmagan, rune-scientist. Ronon Dex, winged soldier. On the waystation of Atlantis, they're about to become embroiled in an age-old war against a brutal enemy.

~7,000 words; written for the prompt 'woodland fairies.' Additional note about the prompt at the end of the story.
Summary: A sorcerer captures John and his band of adventurers and turns them into fairies. Problematic, but not fatal – as long as they can avoid being eaten by dragons.
